New east coast low to hit NSW coast

A new east coast low is threatening to deliver more wild weather to the NSW coast.

It is not expected to be as intense as the low that caused last week's devastating storms that killed four people and caused widespread flooding and damage from the mid-north coast to the Illawarra, the Bureau of Meteorology (BOM) says.

But BOM has warned the community and emergency services to be on alert.

The initial impact of the storm is expected in the mid-north and northern coasts from Thursday, with the possibility the system may track south towards the Hunter and Sydney metropolitan areas later in the week.
